PySQL

A switch to git was undertaken and the source tree was and reorganized slightly. Useless and dead modules were removed (pysqlio and pysqlnet). The license was changed from GPLv2 to GPLv3. Unicode is now used inside PySQL. Oracle client encoding (NLS_LANG) is honored for database I/O and terminal encoding for user I/O. Unit tests were added. A new function parser that allows more complex and useful command switches was added. Graphical functions (datamodel, diskusage, etc.) have new options.
